Benefits of technology

The present invention is about a golf club head with a frontal acoustic chamber and a rear weight saving chamber separated by a panel member that bifurcates the golf club head. The second material has a lower density than the first material. The front to rear volume ratio of the golf club head is less than 0.35. The panel member curved away from the striking face, and all three panel members are placed at different angles relative to the striking face. This invention has improved sound and weight properties for golf club heads.

Problems solved by technology

However, despite the potential gains in the discretionary mass gained by the utilization of such lightweight material, the utilization of such material usually comes with some drawbacks.
More specifically, the utilization of such lightweight material may generally come with an undesirable acoustic characteristic, making the golf club undesirable to a golfer irrespective of performance.
Despite the above, none of the references provide a method to improve the performance of a golf club head by providing a way to improve the performance of a golf club head utilizing advanced materials all while providing a clean way to address the degradation of the acoustic characteristics of the golf club head.

Abstract

A golf club head that is capable of preserving the metallic acoustic signature of an entirely metallic golf club head all while utilizing a lightweight composite material is disclosed herein. More specifically, the golf club head in accordance with the present invention creates a frontal acoustic chamber in conjunction with a rear weight saving chamber via a panel member barrier is disclosed.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to a new and improved golf club having a secondary barrier behind a striking face portion via a panel member. The panel member allows the golf club head to incorporate exotic materials at the rear aft portion of the golf club head without sacrificing performance. More specifically the secondary barrier preserves the acoustic characteristics of a metallic golf club head while allowing the rear aft portion of the golf club head to be made out of exotic materials that may generally degrade the acoustic characteristics of a golf club head.BACKGROUND OF THE INVENTION[0002]The utilization of lightweight materials in a golf club head is generally known. The utilization of lightweight materials in a golf club head removes mass from specific portions of the golf club head and allows it to be redistributed to more optimized areas. U.S. Pat. No. 6,612,938 to Murphy et al. illustrates one of the earlier attempts to use exotic m...
